TO ALL .WHQM IIT-*MAY (L'Clilhlith: l

Be it known that I, T. PEPPER, of the city, county, and State of NewYork, have invented a new and useful Improvement i'n Sewing-Machines, ofwhich the following is a full, clear,iand exact description, referencebeing had to the accompanying drawing, forming a part of thisspecification, and in which-- Figure l represents a partly sectionallongitudinal elevation of a sewing-machine, or machine in part, inillustration of my invention. p e

Figure 2, an irregular transverse sectional elevation of the rea-r ordriving portion ofthe machine, and Figure 3 a partly sectional plan, ortop view, of the bed portion of the machine. Sirhilartlet-ters ofreference indicate corresponding parts. This my. invention has referencemore particularly to those descriptions ofisewing-machincs which 4employa narrow sewing-table', such as are used-in the manufacture vof bootsand shoes, also applicable, however, to various tubular 'and other work;

'Mv invention, in this connection, consists, irstly, in a certaincombination of means for effecting suchvariab'le action or feedyalso,inA combination with afeeder, operating substantially as described, of aswinging or curvilinearly-oscillating shuttle; and, furthermore, inconnection with afec'd arranged at the end ofthe table,-

ef a double pinion and rack arrangement er combination for operatingthe'shuttledriver, and whereby the reciprocating 0r drivingrack may havea full motion given it to oscillatethe shuttle curvilinearly withoutprotiurt ing or working beyond the end ofthe table to interfere with thework on the table, or limit its position thereon relatively to theextreme end or point ofthe table. y

Referring to the accompanying drawing, A. represents the frame or boxportion of the machine, Bits goose-neck, and C the narrowwork-supportingtable. D is themain or operating-shaft, which ismad'e torevolve by any suitable mean-s, `and E the needle-bar, with needleattached, actuated by'a bell-cranked v.arm or lever, LTS, (J1-lat gearswith a grooved cam or' disk,'G, fast on the shaft D, while another armorlever, II, operated hy a' revolving stud, a, inlconnection with saidshaft, serves, in conjunction with a spring, 6, to give the.ne`ee.=saryintermittent reciprocating action to the presser-foot I, to insureits'timely hold on and release of the material orarticle bei-igStitched. J is. the bobbin-holder at the rear-of the machine, fromaspool on which the needle-draws' its supply of thread, 'and-K is aeurvilinearly-rcciprocating shuttle, for carrying the locking-thread andpassing it through'the loop .of the needle-thread, as wellunderstood inother sewing-machines, but which shuttle is here 4arranged in a race foroperationclose to the front end of-the table C,in connection with theneedle and a-feeder,

L, situated at the end. of said table, and having a'. peculiar action orcombination of actions as hereinafter described. M is theshuttle-driver, hung on a vertical shaft or axis, c, and having areciprocating 'curvilinear motion Acommunicated to it by means ofpinions d e and a racI-:,f, driven by an eccentric, X, on the main shaftD.

The reason for thus operating the shuttle-driver by piniona' cZ-and e,theone in rear of the other, and the rack in gear with 'the rearmost,is, in an arrangement such as this where the sewing and feeding-devicesarc situated close up to the forward end of the table 0,4 to givensufficient ylength of 'throw to the shuttle-driver without the`protrusion of the -raclc initsl forwardstroke, through the end of-'thctable, which would he the case were the rack in direct gear with thepinion d, and would interfere with the work being'manipulated close11p-to the end of the table, and thus the advantages incidental to theAarrangement of the feeding and .sewingA devicesbe counteracted or lost.y l

Thefeeder L, thatmay lbe serrated, and plays in or throughfa-noteh oropening, g, intheforward-'ond of 'the table, isy hung on, attached to,or forms part of a rod or bar, 71 running from front to back kof themachin@ and is' free to reciprocate longitudinally, or topartly turn oroscillate in its bearings,a`ccording to tho'direetio'n required to givethe feed. This rod t carries'` arms or levers N O, which are operatedrespectively, the one, N,

by either of two cams, P Q, flattened or swelled, say,l as seen' at if,intg. 1, to produce, in connection with a spring, gli, a longitudinalaction of the rod h and feeder L, while the other lcveigb, isv operatedby swells cream formations It'. Z, to give, in connection with a spring,S. au 'oscillating motion to the rod nand transverse action? "meer tothei'eeder. The cams P Q and cam formations k Z are all. made in, on, orcarriedby, and constitutes sliding-clutch, 1, on the main shaft, withwhich it tur-ns, so that, by means `poi' a clutch-lever, VU, fitting andlocking into notches on m1 m2 ma, either one of the cams, P Q, may hethrown into gear with the lever N, 4or cam formations 71 Z intogear withthe lever 0'; and these cams or cam formations are so pitched as to varytheir time `or times of action (relativelyto the action of the needleand presser-foot I;vthat is to say, when the lever U is in p hack withthe not'cii m, their .the clutch 'l throws the cam Q into ear with thelever N so as to' ive sa an g 2 g a y 4intermittently-reciprocatinp;longitudinal forward feed `to .the feeder L,relativelyto thcaction ofthe pr' esser-foot l 11 while, when the lever U is thrown into lock withthe notch m1, then the longitudinal feed ot' the Ifeeder L is, 'byreason of the formation, oh the periphery, of the cam P, with which thelever N is in gear, in a reverse or back direction. The same principleof action applies to the lever o in its gear with either of theca'mformations il: Z, hysliding the clutch T, and locking thelever U in thenotch m or m3, the forrmttions k. or4 Z being softimed `or pitched,relatively to the action ofthe needle and presseri`oot I, as to give tothe :materialeI transverse feed, the one to the right and the other tothe left, as occasionl may require. Adjusting-Screws, V W, may beused toregulate the extent of feed in either of these directions, by shiftingthe positions oi`-thelevers NVO'relatively to their i fffifingains. v

Fruulhis description it will be seen that not onlylinay the feed he aforward oueyat the ektrcmecu'd oi' thel table, ihtia tilowing the workto be closer manipulated, say, in the case of a boot or shoe, up totheverytoe, but

that, without shifting the work, which, for cross-stitching, as intubular worl it is not always practicable to do,

the feed oi' thc work relatively to the needle may, by adjustmentthroughthe lever U ofthe clutch T, be inado i longitudinally, forward,backward, or transversely, to the right or left,across the `table C,andtliis withoutvof necessity stopping the machine, hut simply changingthe action of the clutch T through its cams 'or cam forma tions upon, inpoint oi' time relatively, the action of the presser-foot, the levers Nor O.

What'is here claimed, and desired to be sccured by Letters Patent, is il. The combination of the sliding clutch T, with its cams or camformations, levers N O, and rod 7i, with `its feeder L, for operation inconcert with a presser-foot, I, as herein yset forth. I

2. The combination of the reciprocating shuttle K, with the feeder L,needle, and presser-foot I, at 'the cxtreme forward end of the table C,allconstruct-ed and arranged iis shown` and described.

8. In combination with the shuttle-driver, M, at or near the forward'end ofthe table C, the pinions d e and raclrf, substantiall)r as andfor the purpose herein Set forth.
